OPERATING TEMPERATURE ºC
Pressure rating procedure 1. For applications at elevated temperatures, the pressure rating must be multiplied by an appropriate temperature derating factor obtained from the temperature derating chart above. 2.. These working pressures are not necessarily valid for system components. Prudent system design requires that all other system components be evaluated for their specific proper pressure capabilities.

The thermowell design has PASSED the wake frequency calculation“These well design calculations are based on the ASME power test code PTC 19.3- formulas. The results of these calculations
should only be used as a guide for thermowell design. Temperature Controls does not guarantee the performance of a specific
well design obtained from the use of these calculations”.
